Ideacentre B520 Bios Recovery

Hi,
I would like to know, if there is a BIOS Recovery function for the IdeaCentre B520. Something like the normal Recovery-function for AMI-Bios with AMIBOOT.ROM on an USB-Stick or a Jumper on the mainboard.
I need this just for my documentation. If there will be a BIOS-Update in future, I could be sure, that I can recover my BIOS in case of a bad flash.
If there is no such option, were is the BIOS-chip located on the mainboard?
With best regards,
nordicboy

That would be very interesting, if there is such a recovery option! Is there a step by step instruction? Does it even exist?

IdeaCentre B520 display backlight issue

I have a Lenovo Ideacentre B520 All in one. It powers on alright. But the LCD backlight does not come on. I can see a faint picture on the screen if i use a flashlight. The unit's Backlight converter board i noticed the capacitor on it is damaged. I can order a new board and replace it (easy enough). I was wondering if this is a common thing on these all in one units? Another person told me it could be the mainboard of the unit. I'd rather spend about$50.00 than 189.00. Also when i hook the unit to HDMI out and use a external monitor i see the lenovo splash screen, but when i install a hard drive after the BIOS screen it locks up and i have to restart, but if i do not install a hard drive, then i can boot ubuntu or memetst (just for testing purposes). Any ideas?

Yes, at maximum brightness level the backlight bleeding is very visible but I use it at 5 or 6 level where it has excellent contrast ratio considering how crappy current notebook displays are in general. The uneven backlight is caused by fancy LED backlight which is still not able to deliver similar quality regarding uniformity as good old CCFL backlight (that's why professional LCD monitors still rely on W-CCFL backlight). But I agree that the top-left corner is way too much bad and might indicate that the panel is seated badly in the frame. On the other hand my old IPS panel in R51 also have backlight bleed at maximum brightness level.
Major problem is that Lenovo is still not able to fix the stupid bug with brightness level always set to max in BIOS screen that the backlight bleeding is very visible and irritating everytime you boot your machine.
IMHO, the X220 IPS panel is still much better than any ugly contrastless TN panel Lenovo puts into ThinkPads (except 15" FHD). I bet that you would hate the X220i TN panel more than this one
There are also two different revisions of the IPS panel, the second one fixes problems with image retention. As for comparison with Z60m, X220 display lid is much more fragile so the panel is not protected well against pressures and flexes. In any case panel flex should affect the backlight bleeding temporarily only. If it persists it is subject to repair (replace, reseat etc.).
Unfortunately I don't have any good low-light camera that takes useable pictures in dark environment so I can't post relevant images of the backlight bleeding.

Toshiba A105 BIOS Recovery Process Questions

Hi!
Ive got a Toshiba Laptop A105-S4284, Model #: PSAA8U-0FH02K that froze while trying to flash the BIOS. Now, when I try to boot it up, it gets stuck in the same place it did during the flashing; on the Toshiba splash screen with the status bar at the bottom showing about 20% complete. Options available on this screen are: Press F2 for System Settings and F12 for Boot Menu. Pressing F2 results in a beep and the status bar is replaced with the text "Please Wait..." but nothing else happens no matter how long I wait. Pressing F12 doesnt do anything. Pressing ESC takes me to a screen that shows the typical system info -- Phoenix Technologies Version 6.00; Intel Calistoga CRB.T3A Reference BIOS; VERSION.MAK 1.53. It looks like its at least partially POSTing since it shows CPU, Cores, No TPM or TPM has a problem, and system RAM and stops there. I cant get into the BIOS and cant boot into Windows.
Ive read the posts on here regarding the BIOS Recovery Process and was hoping someone could provide some clarification for me, especially since Ive already waited a week with no reply on another tech support site forum. :-(
Anyways... Ive downloaded the Crisis Recovery.zip files to create a Recovery Disk and am trying to follow the instructions.
There are a bunch of files in the .zip and Im not sure exactly which files I need to have on the boot disk Im creating.
The files in the .zip are:
- crisboot.bin
- CRISDISK.BAT
- makeboot.exe
- minidos.sys
- phlash16.exe (actually PHLASH16 version 1.6.5.4)
- wincris.exe
- wincris.hlp
Ive downloaded the BIOS Update from Toshibas website for the A105-S4284. Which file do I need to rename to BIOS.WPH and add to my Recovery Disk directory? Do I want "s10gm600.rom" or "1988d600.ima"? I extracted the file from the bootable BIOS installation diskette (1988d600.exe) to get the 1988d600.ima file.
I ran wincris.exe and only the following files end up in the directory Ive designated for my Recovery Disk:
- BIOS.WPH
- MINIDOS.SYS
- PHLASH16.EXE
Do I need any of the other files from the original .zip?:
- crisboot.bin
- CRISDISK.BAT
- makeboot.exe
- wincris.exe
- wincris.hlp
If someone could provide some clarification on which files to use and most importantly, if those are the correct files for the laptop Im trying to fix. I think all the posts Ive read are for laptops newer than this one and it seems the secret to succeeding at recovering a BIOS is using the CORRECT files. Ive searched all over and cant find any posts from someone with an A100/A105 who has been able to do a BIOS Recovery from a CD, USB floppy or USB flash drive.
Is there ANY hope?
Thanks in advance for your time and assistance with this; its GREATLY appreciated.
Sarah ;-)

Hi Sarah,
I had the same thing happen to my A105 4094. I've looked at some of the other blogs, but I'm not sure if I should try the corrective action they suggest. Not sure how common the different models are.
I'm going to keep trying to resolve this. If I find something that works, I'll write again and let you know. Please do the same for me and other A105 owners.
Thanks,
Jamie

DV6-6000 LF372AV - Fails BIOS recovery

I have a DV6-6000 Prod #LF372AV where the BIOS became corrupted. Didn't attempt update, just failed out of the blue.
First symptom is turn on PC, hear fan come on then immediately reboots. Stuck in this cycle of rebooting forever. With no error codes (such as not even Caps Lock LED blink) I guessed corrupted BIOS.
I tried the Windows+B, but I've wiped this harddrive previously and the BIOS recovery partion was gone.
So, I downloaded and ran the HP UEFI Support Environment Softpaq as directed here:
     http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c02693833.
This partially worked. With a Recovery BIOS loaded on the the USB flash drive, I can hold Windows+B at power up and BIOS loads off the USB key. However, it is NOT replacing the corrupted BIOS on the laptop.
According to the instructions, once the temporary BIOS is installed, a reboot should automatically occur. Instead, NOW it stays on (no more spontaneous reboot cycle) and I get a 2 blink error code out of the Caps Lock LED. It seems that the temporary BIOS loads into BIOS memory, but the stored BIOS itself cannot be overwritten. As I stated earlier, if I reboot, I'm back to the original condition.
So, it appears that the BIOS storage is bad. ???
Even if that is the case, I don't understand why boot into BIOS stops at the error indicating BIOS is corrupted. Obviously the mem copy of BIOS run off the USB flash drive is "more functioning" than the stored BIOS, but I still can't get far enough to get to the BIOS editor or any BIOS update utility.
I tried a second method. I downloaded the latest BIOS for this model laptop from HP support. Then I extracted it and ran the updater. It extracted an even newer version of the BIOS recovery tool onto my flash drive. This had the exact same results as the UEFI Support Environment version of BIOS. Therefore, two different versions of BIOS have failed to repair the corrupted BIOS and have failed to get me past the caps lock LED blinking twice.
Any help would be most appreciated.

Hi
Workaround:
There are few steps that has worked for few but not always..
Restart and tap F2. F2 will show an option “BIOS Management” . Select BIOS Management and then select “Roll Over to the previous BIOS”
BIOS Management option will not be available if the system do not have HP_Tools partition installed or if it is deleted.
Fix if BIOS Management is not available
i)                    Press and Hold the Windows Key and B key at the same time when the system is turned off or follow the steps from this link: Recovering the BIOS using key press combination
ii)                 Shutdown the Notebook. Remove the Hard Drive and then turn the computer ON and tap F10 to load BIOS. If it loads BIOS then it should rollback to previous BIOS or it might show a black screen. Just leave the system ON for about 2-3 mins and turn it on with the hard drive and check.
Let us know how it goes!

Hi!
You can download new BIOS versions on the Toshiba website. Search for your model and select BIOS update
http://eu.computers.toshiba-europe.com
Download the right file and follow these instructions:
Extract the zip file containing the BIOS upgrade to a temporary folder.
Make sure that all open files are saved and all applications are closed.
Execute the extracted *.exe file in the temporary folder. Follow the instructions on the screen.
The BIOS update will be done automatically.
After a few minutes the Notebook will restart automatically.

Lenovo IdeaCentre B520 - Plug in a Vhs and record my old vhs tapes!

Hi!
Besides of all i want to thank you for the time you gonna lose to read this post.
I bought a lenovo ideacentre B520 and i want to record my old vhs tapes.
I plug in the VHS into the AV in ports (yellow, red and white) and then i switch in the monitor to the av mode.
I can see the vhs tape in my computer but the problem is that i cant control the pc mode. I'd like to know how can i record the vhs tape in Av mode.
Thanks for the help, and sorry my english writing...
Cesar

You'd need to tell us what kind of film and cameras you have. I think you'll need to buy some equipment to do that.
An alternative is to send your film to a place like Integrated Imaging and they could transfer it to DVD or another suitable format for iMovie.

IdeaCentre B520 - sound recording too low, sound on Skype too low

Hi
When I speak on Skype or use Sound Recorder to record my voice (using internal microphone), the sound is very low.
I think I have turned up every possible Microphone and Audio setting on the system to its highest.
My IdeaCentre B520 is very new and I haven't installed anything else on it other than Skype.
OS is Windows 7 x64.
I used the Lenovo automatic check for drivers and it said all drivers up to date.
I haven't had a system with an internal microphone before, I literally just talk (loudly) at the monitor, I presume there isn't anything else I need to do?!
Thanks for any help you can give with this frustrating problem!
Patricia

Hello Patricia,
This is not good to know that you are encountering the issue with your new desktop.
Please make sure that the Audio driver version is 6.0.1.6294, if it is not then you may download it from the mentioned below web link.
http://consumersupport.lenovo.com/ie/en/DriversDownloads/drivers_show_4706.html
If the version of the driver is same then you can try the settings.
1. Right-click the icon of the speakers icon at the notification area, and then click “Sounds
2. Click the tab “Recording”, and then click “Microphone” à select “Properties”.
3. Select the tab “Listen”, and then check “Listen to this device”. Apply it, and the function will be enabled.
Best Regards,
Tanuj

Dv6-2000sl USB BIOS recovery

Hi guys, i'm kri.
i have a HP Pavillon dv6-2000sl that present double led blink(capslock & blocnum) I saw that rapresent bios curroption error.
The uefi partition on harddisk called HP_TOOL was empty (contains only SystemDiag Folder).
I'll want to create an USB UEFI bios recovery while i saw on the hp forum, but is inefficent.
The files that i find in BIOS package (support/dv6-2000/driver/ecc) wasn't the same file that the guide use to restore BIOS via USB. The guide isn't specific for this pc and the other online guide(not official) used or CAB.rom package o same files colled bios.wph or other exstensions.
i could know that files copyng on usb after formatting(hp format tool?) (uefi support assistant??) and that executable put it in to recived the feedback in this page : http://h10010.www1.hp.com/ewfrf/wc/document?docname=c02723600&lc=it&cc=it&dlc=it (HP BIOS UPDATE)
Thanks a lot, im in panic.

Hi @kridrina
Welcome to the HP Support Forums!
I understand that you are getting a double LED flash pattern on startup, meaning a BIOS problem. I am happy to help.
Had you deleted the contents of HP_Tools at some point in the past?
It sounds like you went straight to trying to make a usb flash device to repair/reinstall the BIOS. Have you tried a basic BIOS restore from the saved image? Mainly using the Windows+B combination as described in this page.

X121e (x120e x130e) Bios recovery help

Hi everyone. After my x220 thread was left unanswered , I hope I'll have better luck with this.
I need bios recovery procedure for x121e ( x120e , x130e).

It would be very helpful if anyone who successfully recovered x121e would post here.
It it means anything, its with amd e450 apu and its japanese version which has Japanese keyboard.
Kind Regards
Solved!
Go to Solution.

[Solved]
Fixed it!
So for everyone with same model and same problem: It turns out this bios really don't boot-block. So failed bios = paperweight brick without recovery options.
But this is how I solved mine. Bought a SPI programmer, ic test clip (soic8) , some wires and made adapter to connect clip ind programmer. Had some problems , and had also to modify downloaded bios since I didnt have good backup but after little playing it fired right up. If you have good backed up rom, flashing should be easier. This is solution for those with more technical skills , but much easier than soldering the chip.

HP TX2510US Bios Recovery

Hello,
My laptop would freeze on occasion so i decided to update the bios and it froze during the upgrade. When i now power it on i get the num lock and caps lock lights and they blink twice which indicates a corrupt bios. I get nothing on the screen. Is there anyway to fix this? replacing bios chip? bios recovery jumpers? Please advise

I am currently having the same issue as the original poster. Mine happened randomly I was using my laptop just fine yesterday and then turned it off and tried starting it up today and got the issue because it first got to the login screen and then locked up.
Any information or input would be greatly appreciated.
